The arch of the foot is a very complex structure, consisting of multiple bones and ligaments. Most causes of arch pain are related to the anatomy of the arch and the types of physical activity that you perform. For example, a classic set up for arch pain is people who engage in lots of high impact exercise (such as running) while wearing a type of athletic shoe that does not properly support their type of foot arch. If you notice that the twinges of pain you have are most commonly associated with or immediately after exercise, you might want to visit a good athletic shoe store to make sure you are wearing the right kind of shoe.
Another cause of arch pain is plantar fasciitis. The plantar fascia is a tough tissue structure that holds the bottom part of the arch in place. The fascia often becomes inflamed and sore, usually as a result of repetitive motion (for example, very common in those who stand on their feet for work). The pain is often noticeable first thing in the morning and worse with activity. In addition to wearing good arch supports and taking anti-inflammatory medications, stretching exercises are often a part of the treatment.
